      I just now installed it on my work pc and no errors to report. I even checked event logs and it was installed successfully with no errors.

      The error reported appears to be related to good old flash player for windows 10.

      It seems like the first question we need to ask folks when they run into issues with the monthly updates is “what anti-malware/anti virus are they using?” It seems to be a common theme over these last several months.

      0x800f0988 is not new, it happened before in numerous versions. Seems to be something missing in WinSXS folder, possible due to a registry value handling superseeded components.

      deeper research here:
      Deskmodder.de

      quick resolution: inplace upgrade.

      They have been working on a resoulution for that error since v1809 😀

      it does not have a fix except in-place upgrade
      or manually restore all RTM components from vanilla ISO to WinSXS folder (for experts)

      I would be curious if anyone tried removing flash from windows 10 and then re-enabling it in order to fix the situation.

      I’ve experienced this error on 1909 and the following worked from my notes.
      In an admin cmd type – dism /online /cleanup-image /startcomponentcleanup
      followed by (once complete) – dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase  then restart device.

      I’ve got the same problem. Waiting is probably just what we all need to do. ^^

      My computer, especially the mouse, are extremely slow after the last W10 updates. Is this a common problem and is there a fix or work around?

    • #2289121

      extremely slow after the last W10 updates

      What is slow? Startup, loading programs, typing, etc?

      Open Task Manager (right click on the task bar) and see if Windows is using lots of CPU, RAM or disk?

      cheers, Paul

        In the end after spending lots of hours experimenting and trying to identify the root cause, this was fixed by using the sledgehammer approach of getting a current ISO of the uupdump Feature update to Windows 10, version 2004 (19041.508) and performing an upgrade in place. Use at your own risk. The uupdump is not an official image, but I have enough checks in place to trust it as being like the original if not better and more useful in some aspects. 😉
        https://uupdump.ml/
        The likely root cause of the update failing to install is a bug in Windows 10 clean-up mechanism in relation to the Optional FOD components and in combination with the en-GB Language Pack.
